The counties involved in this study belong to the Piedmont
Plateau. Soils are largely from crystalline rock and except for small
areas of Davidson and Lloyd types, the soils are derived from acidic
rock. The soils of this area are deficient in phosphorus but are fairly
well supplied with potassium. In most cases lime and phosphate are the
limiting factors in securing high yields of pasture and forage crops,
and in getting stands of certain legumes.
